Zmanjšanje faktorja skaliranja hitrosti razvoja navora po 6-tedenskem unilateralnem izometričnem treningu z uporabo elektrostimulacije ali voljnih kontrakcij

Key Points

Torque development scaling factor increased significantly after six weeks of training, showing positive muscle adaptation.
Maximum voluntary isometric contraction also improved, with increases of ~29% in maximal torque and ~13% in rate of torque development metrics.
Participants underwent a rigorous intervention involving electromyostimulation and voluntary exercises, assessed before and after training.
Findings indicate that both training methods yield similar benefits, highlighting the effectiveness of each in enhancing muscle strength.

Abstract

This study explored the changes in the rate of torque development scaling factor (RTD-SF) and maximum voluntary isometric contraction (MVC) variables following six weeks of unilateral isometric electromyostimulation (EMS) and voluntary (VOL) exercises. Twenty-six physically active participants were randomly assigned to EMS (n = 13) or a VOL group. MVC and RTD-SF of the quadriceps femoris of both legs were assessed before and after training. EMS and VOL exercises had identical frequency (three sessions/week), intensity (60% MVC), volume (40 contractions), and work-to-rest ratio (18 min: 6.25 s of work/20 s of rest). There were no between-group differences for the trained leg with overall increases in maximal torque (Tmax) of ~29% (d = 2.11–2.12), ~13% for RTDmax (d = 0.92–1.10)
